[QUOTE="noel carlson, post: 924839, member: 16138"] I am not a paid advertiser on this site... so in keeping with forum rules, my comments will be limited to a technical discussion. John has graciously offered to contribute his time/resources in assisting with the development of a Mach 3+ loading for the ZA projectile/barrel "system". All who have read the link to Sniper's Hide know that the issue of bore heat-erosion at extreme velocities has been addressed. Common barrel alloys will have a reasonable life, perhaps even above that of normal loadings, with the ceramic bore-lube currently used in conjunction with the solid copper ZA projectile. What has not been established (yet) is the possiblity of reaching the next velocity accuracy node within the MV potential afforded by RL-50. It seems pretty clear to me that 3,600 fps is obtainable with an additional 4-6" on John's barrel. If he can obtain a sub-half MOA accuracy with the 280 grain projectile between 3,400-3,600 fps, I will consider his experiment a success. We may have to adopt a bull pup configuration to make it ergonomically practical, but the overall goal is well within reach. Any questions? [/QUOTE]
